摘　　要：由于城镇污水厂尾水污染物种类繁多、浓度和流量波动大,因此净化工艺较为复杂,净化效果较差。研究泗洪县地形等概况与近自然氧化塘人工湿地净化机理,预估污水处理量,规定净化前后水质标准。考虑地形地势和水流设计湿地结构,采用化学需氧量测试仪检测、稀释接种法等方法检测COD、BOD_(5)、NH_(3)-N、TN、TP等污染物的含量。结果表明,利用该方法净化城镇污水厂尾水复合污染物后,COD、BOD_(5)、NH_(3)-N、TN、TP的污染物浓度分别为8.0 mg/L、3.9 mg/L、5.0 mg/L、3.1 mg/L、4.4 mg/L,污染物去除率均超过50%。由此证明,该方法能够净化尾水中污染物,净化后的尾水质量较高。Due to the wide variety of pollutants,high concentration and flow fluctuation in the tail water of urban sewage plants,the purification process is relatively complex and the purification effect is poor.This paper analyses on the topography and other general conditions of Sihong County and the purification mechanism of near-natural oxidation pond artificial wetlands to estimate the sewage treatment capacity and specify the water quality standards before and after purification.Consider the topography and water flow to design the wetland structure,it uses chemical oxygen demand tester,dilution inoculation method and other methods to detect the content of COD,BOD_(5),NH_(3)-N,TN,TP and other pollutants.The results show that after using this method to purify the composite pollutants in the tail water of urban sewage plants,the pollutant concentrations of COD,BOD_(5),NH_(3)-N,TN,TP are 8.0 mg/L,3.9 mg/L,5.0 mg/L,3.1 mg/L,4.4 mg/L respectively,and the pollutant removal rate is over 50%.This proves that this method can purify the pollutants in the tail water,and the quality of the purified tail water is high.
